Resumen:
Synopsis We present theoretical calculations of electron impact multiple ionization of rare gases (single to quin-tuple for Ne, Ar, Kr and Xe). The theoretical model used is the CDW-EIS, adapted for electron impact, and the first Born approximation for the high impact energies (E>0.6 keV). The results presented here take into account the direct and the post-collisional ionization. The latter by including experimental branching ratios of Auger type processes. This formalism describes the experimental data quite well. In the case of Kr and Xe we obtain good tendency even for sextuple ionization
